+
+Side-effect-free alternative for `localize` (the globally shared instance of LocalizeManager).
+When this function is imported, no side-effect happened yet, i.e. no global instance was registered yet.
+The side effect-free approach generates:
+
+- smaller, optimized bundles
+- a predictable loading order, that allows for:
+  - deduping strategies when multiple instances of the localizeManager are on a page
+  - providing a customized extension of LocalizeManager
+
+Also see: https://github.com/ing-bank/lion/discussions/1861
+
+Use it like this:
+
+```js
+function myFunction() {
+  // note that 'localizeManager' is the same as former 'localize'
+  const localizeManager = getLocalizeManger();
+  // ...
+}
+```
+
+In a class, we advise a shared instance:
+
+```js
+class MyClass {
+  constructor() {
+    this._localizeManager = getLocalizeManger();
+  }
+  // ...
+}
+```
+
+Make sure to always call this method inside a function or class (otherwise side effects are created)
+
+Do you want to register your own LocalizeManager?
+Make sure it's registered before anyone called `getLocalizeManager()`
+
+```js
+import { singletonManager } from 'singleton-manager';
+import { getLocalizeManger } from '@lion/ui/localize-no-side-effects.js';
+
+// First register your own LocalizeManager (for deduping or other reasons)
+singletonManager.set('lion/ui::localize::0.x', class MyLocalizeManager extends LocalizeManager {});
+
+// Now, all your code gets the right instance
+export function myFn() {
+  const localizeManager = getLocalizeManager();
+  // ...
+}
+
+export class myClass() {
+  constructor() {
+    this._localizeManager = getLocalizeManager();
+    // ...
+  }
+}
+```
